Specification of Letters Patent.

Patented July 2 1', l 908 App'um'ion and January 1o, 1901. serial No.42,767.

To 4all whom it may concern:

' l Be it known thatl,A WALTER J. Bannon,

citizen of the United States, an'd resident of theV borough of Brooklyn,cit t of New York, in the county of Kings an l State of New York, haveinvented' certain new and useful Improvements in Type-Writing Machines,of

`which the following is a specification;

Thisinvention relates to tabulating mechanisms used upon typewritingmachines, and

more particularly'to those in which any one of a series ofdenomination'keys maybe pressed 'both to project` its associatedcarquires pressure upon `the denomination key.

i `for too great a-length of time.` If the key A' broughtto apositionover the Writing keys should be releasedbefore the carriage hascompleted its run, the latter would come rema-turely under the controlof the letter eeding mechanism, and, if this' were not' noticed by theoperator, the writing-of the number would be commenced out of;column, orout of' proper position. "l

Therefore one of the .objects of my invention is to provides mechanismwluch shall .not require the ressure upon the key to be maintained untithe cooperative members of` the carriage-arresting mechanism have comeintoengagement, so as thereby .to enable thehands of the operator to bemore quickly for operation thereof after the carriage has been arrested,and also to insure that when the key has once been. ressed and the stopset and thecarriage re eased, it will be impossible for the carriage tocome to a halt at any point short of that predetermined by the selectedstop. n

In carrying out i nyinvention, I cause both the operated denominationstop and the car' 'riagereleasmg device to hecomevautomatically lockedin working position, vso that, althoughthe operator may immediatelyrelease thekey, fthe carriage may still com. 'plete its run 'and bearrested at the proper point. l furtherv provide means for auto- -vofarNo. 6l Remi matically unlocking thedenomination stop and its.connected mechanism, including the carriage releasing device.

My invention consists broadly in the combination with a series ofdenomination stops oa series of latches; and it further consists in thevarious features of construction and combinations of devices hereinafterdescribed and i particularly pointed out in the appended claims.- l

yFrom a basel rise corner" osts` 2, rwhich sustain a to -plat 3,lipon'w, 'chl-are sup- --ported type ars 4, the latter being connectedby .rods 5 'to-horizontal levers 6, pivoted in v'rear upon a commonfulcrum bar 7 and having at their forward endsfkeysS. A transl verseuniversal vbar '9 beneath the levers is hung by' rods 10 upon branches 11 of a vibratory framev which is 'ivotedv at 12 upon a listed-bracket13. -Sa1d frame comprises anA upright arm 14, upon the upper end ofwhich are mountedv a stepping dog 15- a'nd a detent dog 16. Saiduniversal bar is normally held up against the key levers by a dog-rockerspring 17.- yIn engagement with the stepping vdog 15 is an escapementwheel 18, which Ais suitably connected to a pinion 19 in mesh with areleasable rack 20,`the latter being attached to the front ends of arms21 hinged at 22 to a carriage 23, to which is connected a latenirame24.` riage 23 1s supported, `by means of' rearwardly extending arms25, a" rack 26, upon which may be arranged any number of suitable columnstops 27.

A set of Upon the carv upon a` bracket .41 fixed upon the top in rearofvthczcolumn -stoprrack, and suitably supported upon the upper part ofaframe 29,

which may be attached to the rear end of the machine base in anysuitable manner, as by screws 30. .aEach of the denomination stops is ofplate-like or blade-like formation, and,

by means of a horizontal slot 31' vworks upon horizontal cross bars 32fixed in the frame 29.

Normally the blades stand a little inrear ofv the column stop rack, andare movable forwardly upon the rods 32 so as to project into thc path ofthe column stops. Each'blade Acarries a lug 33- for engaging a bar 34ofabail or U-frame, the arms whereofare designated as 35 and are pivotedat their lower ends at 3'6 upon the frame 29. One of said arms isextended at right anilesforwardlyfrom the pivot 36asat 37, and isconnected by an upwardly-extending link 38 to the rear end `of acarriage-release lever 39, whichl isjpivoted, at

plate, and extends thence forwardly beneath the carriage'rack 20sothatfit may lift the latter out ofmesh with the pinion 19.

The denominationfstops are operated, ,by

meansof a set of vertical levers 42 of. the

. having returning springs 46.x

' ltodetain their respective levers 42 and their' bare well-known.

ing sustained in any Asuitable manner, as by` forwardly extendingthreaded y Wires 51, which are tapped intoth'e top plate at 52, andwhich nay also serve as attaching devicesffor the upper, end of frame29.V AA l coli-ed spring 53 (llig 2) may be strung'over thev 'forwardportums of kthe latches 'andcaughtupon screws 54 tapped into the' arms50 so as to hold or snap the latches down.-`

flhese lat-ches are designed to catch over the upper forward edge of thecatch. bar 49, so as appurtenances in working position. In yorder thatsaid gua-'rd bar maybe ad justed closely, l tap into it a horizontalscrew 55, the rear end of which bears against the frame 29, so that whens aid'sc-,reu is .turned in one direction or the other, the said guardispressed away from or permitted to spring towards said frame by reason ofthe resiliency of the arms 59', alliu-.ir-nut -56 being provided' forpreserving the adjustment.;V f

A universal latch-release bar 57 is arranged horictimtally at a pointforward of the/catch bar 4.9 and just below the noses of the latches,

said rciease bar being lixed upon the rear ondofan arm 58, whichprojects rearwardly from the'dog rocker 14, to whichlatter it is securedby a'screw 59.

'engages -the universal` bar' or bail 34, and

pushes the latter forwardly about the axis 36', and through the bailarn37, link 38 and lever 39 lifts the rack 2() out of mesh-with 'thepinion, thus permittingthe carriage to be driven by its spring intheusnaldrum 62 untilthe column sto 27 engages said pro- 'jecteddenomination lade, whereby the carriage is arrested at theV proper pointto begin the writing of a numberwhose denominatlon corresponds'to theoperated key 45. During the described stop- ,ro'jectingrnovement of thelever '42, its latc 48 is carried forwardly so as to 'catch over the bar49, and thereby detain or lock in workingvv osition said lever and its.associated stop, t1ejrack'2() being consequently supported out of meshrwith the pinion 19, w ereby premature rengagement of the rackwiththepinion is prevented. It will be understood that whentherun or jump ofthe carriage is completed;all of the arts, inclusive of the denominationsto atcli and rack 20, remainin'the describeda normal positions.l -Afterthe carriage has thus been positioned by the tabulating devices, thedesired number .may be written by `manipulation of 4the type' keys 8,Whose 'movements arecommunicated by the levers ,6 andlinks 5 to the typebars 4, each of said Alevers also .operatin the universal bar 9, wherebythe dog roc er 14 eis caused to reciprocate, and the dogs .15 4and 16 tocoperate with `the escapement wheel 18 to permit a st e -by-stepmovementof the aper carriage.

' t will be Iunderstoodthat t e arm 58 and release bar 5 7 vibrate inunison withthe do rocker, and hence at the first depression o any typekey, said arm and release' bar are v swung upwardly, andthe latterengages the nose of` the latch which has ,been described' as. having`caught over the bar 49, and lifts said latch out of engagement with`said bar, whereupon the latch, the lever 42, the stop 28, the rod 44and thekey45 are all returned to normal osition by the reaction ofspring 46, the bail) normal position, and t e rack 2() dropping asusualinto mesh with the pinion 19.

The tdescribed release of the latch 48 and consequent re-connection'ofthe carriage to its letter-feeding devices occur when the key. has madeabout half of its printing stroke, as illustrated by dotted lines atFig. 3, so that by the time said stroke is completed and the rst typeimpression is made, the carriage is again completely under the controlofthe 34-being ermitted to return to` the exact p'oint at which thersttype impression is to bemade so that there may be a drop of sayoneliundredthof an inch or less after the disengagement of thedenomination stop from the column stop and before the type reaches the"platen, this drop'being desirable in order-tosecure a* slight clearancefor' the rack 20, .so thatit may drop freely into mesh with the inion.

sirable that the pinion `be at this time in the precise rotative rackteeth' niayfnot land upon'the oints of the pinion teeth ,fand to thisendsu port upon the cari'viagelrelease lever 39a letent 60, said detentbeinv formed u on thefend'of a bent arm 61, Whidli is rivete to' thelever.

Normally said vdete'nt' stands away-from 'said wheel, as illustratedatFig. 1 ,butat the'disf vengagement of the rack 2Q fromfthe pinionV 1-9,said detentisswung about the `lever 4axisv 40 into engagement* with thel-esca ement wheel, yso as to prevent back-lashvt creol",V whereby therotative positionof the'pmion is preserved, and liencethe rack teethregis- -ter with the pinion notches when.' the carriage is's'ubsequentlyarrested by the oo -v operation of the column stop and denomina- Therack is thus enabled to rebility of aspurious letter-feeding movement ofthe carriage at this time is avoided. Thus it will be seen that when theoperator pushes the denomination key, the denomination stop is ositionedand the feed rack 20 is dis-y engaged) from the pinion 1 9; also vthatboth of said devices are automatically or me chanically locked in theirabnormal positions,y so that the carriage is enabled tocomplete its runindependently of continued rassure upon the key v by the operator, w omay therefore immediately withdraw his and prepare to write.- Moreover,vit w-il be observed thatv the subsequent return of the y denominationstop and the rack 20 to normal position is accom 'lished automatically,or without attention rom the operator.

It will Abe -seen that the letterfeeding mechanism for the carriagecomprises two separable members 19 and separated by the saine key thatprojects a denomination stop 28, thereby ermitting tl'iecarriage to run`until arrested y engagement of the column locating stop thereon with theprojected denomination stop. The projected stopis held in abnormal orworking position mechanically by its latch or detent 48,wliichalso'serves mechanically to del sin the carriage-releasing device39 in abnormal position, thus maintaining the separated letter-feed- -aconnection, through the dog rocker 14, to-

It'is'further de :fof construction and arrangements of parts positionnecessary for -receiving the rack, so' that the points ofl the ada tedto movesaid denominational stops lkeepfthe carriage from control ofthelette'r an er,

20, which may be ing members 1 9 and 2U,.so that by merely pressing anykey of the denomination-determining'. mechanism the correct movement ofthe carriage is insured. The latches 48 have .70' the ty e-operatingkeys 8, so that after one t of' saitFlatclies is set in workingposition, it may be moved out of Working .position by any t.pe-operating key, or by the space-key,-

there y automatically freeing from the control o`f said lat'chboththe-'stop and itsl key,

aswell as the carriage-releasing device 39. Various changes 'maybevvmade in details within the. scope of the invention. The v denominationkeys may be in other form than sliding push keys, -as Vwell known `inthe art...
